Ammonium (NH4+) is deprotinated to ammonia (NH3) in alkaline conditions so solutions need to be sufficiently alkaline (pH’s >9) to allow ammonia to complex metal. Common for use in polyphosphate solutions. Ammonium is often used to complex metals in conjunction with other organic acids such as citric acid.

Take Away: Ammonia with Metals

Take away concepts:
1. At alkaline pHs above 9 ammonia has a partial negative charge and is volatile.
2. The negatively charged ammonia can coordinate with metals such as Zinc, Copper, etc.
3. It takes a high concentration of ammonia to metal to provide any significant amount protection to the metal

EDTA chelates can with stand the harsh conditions of the soil
Efficiency Ratios reported in literature vary depending on soil conditions and can go above 6x in harsh conditions
– Zinc EDTA treatments had concentrations 5 times higher than other zinc treatments (Gangloff, 2004)
– Up to 5x Zinc EDTA efficiency ratios over other sources (Alloway, 2004)
– Zn EDTA increased zinc content of the crop twice as much as zinc sulfate in neutral solutions and up to 6 times as much in calcareous soil (Holden, Brown, 1965)
